' To all whom it may concern.'

Be it'known that I, EnAs'rUs E. WINKLEY, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in AutomaticShoe-Machines; and I do hereby declare the following to be a full,clear, and exact description ofthe invention, such as will enable otherskilled in the art to which it appertains to make and use the same. g

The present invention relates to machines for operating upon boots andshoes in whichthe shoe and operating means are relatively movable totransfer the point of operation of the operating. means around the shoe,and in which the relative movements between'the shoe and means `foroperating thereon are automatically controlled and effected so that theshoe is automatically presented to the operating means as the point ofoperation is transferred around the shoe.

The object of the invention is to provide novel and improved meansl forautomatically correcting the relative position of the shoe and operatingmeans to maintain them in proper relation at the point of operation asthis pointl progresses along` the shoe, whereby the operation of themachine is rendered more uniformly certain and reliable.

To these ends the invention contemplates utilizing some predeterminedcontour or ,contours of the shoe to control and determine thecorrective'movements requisite for maintaining the operating means andshoe in proper relation. By these means the relative movements impartedto the shoe and operating means are made to depend upon the contour ofthe shoe being operated upon, so that each shoe is properly presented tothe operating means, notwithstanding unavoidable variations in shapewhich occur in different shoes, even when ofthe same style andsize.4This also enables shoes of different size and style to be operated uponwithout change Ior adjustment in the correcting mechanism The contour ofthe shoe which may be utilized to the best advantage to control thecorrective movements will depend upon the character of the machine inwhich the invention is to be embodied, and upon the operation which itis to perform upon the shoe. lt will usually be desirable to utilize asthe controlling contour a shoulder or abutment extending along oradjacent to the margin of the shoe sole, or to utilize the surface closeto such a shoulder or abutment.

The broader features of the invention may be embodied in machines forperformmg various operations which are customarily performed uponpartially completed shoes, and may be embodied in mechanisms foreffecting any desired corrective movements4 between the shoe andoperating` means.

In the specific embodiment of the invention shown in the drawings theinvention is embodied in a machine-for sewing the inseam of welt or turnShoes, and is utilized to relatively swing the shoel and sewingmechanism to maintain the channel 'forming` the inner 'surface of thebetween-substance parallel to the line of feed, the corrective swingingmovements being imparted to a jaclr upon which the lasted shoe is sup--ported.. ln this construction the bottom of the channel is the contouron the shoe which controls and determines the swinging movements which'are imparted to the jack to maintain the shoe in'proper positionagainst the channel guide during the feed of the shoe. These swingingmovements are de terlnined b v a fceler which acts a longthe bottom ofthe channel aud causes the jack to be swung 1n accordance with thelongitudinal curvature of the channel at the point where the sewingmechanism is acting on the shoe. .Each shoe is therefore manipulated bythe correcting mechanism in accordance with the contour of the channelin the sole of that particular shoe to keep the bottom of the channel atthe sewing point substantially in line with the line oi the feed of theshoe. i

The :various features of the invention will be readily understood fromau inspection of the accompanying drawings and the following detaileddescription of the mechanism illustrated therein.

'lllO In the drawings Figure 1 is a side eleva` tion of an inseam sewingmachine embody 2 is a side elevation showing the jack swinging the feedof the shoe. The jack `is forced yieldingly toward the sewing mechanisml by a spring bell crank lever 16, the other end of which i engages acollar 1T on the sleeve 7.

, The feeding lawl of the sewing mechanism acts in the usual manner tofeed the shoe, and the shoe is swung to properly guide it ing thefeatures of the vinvention in the forms in which it is preferred toemploy when utilizing the invention to relatively swing the shoe andsewing mechanism; Fig.

ln the machine shown in the drawings the means for operating upontheshoe consists of a sewing mechanism which is similar in construction tothe construction of the wellknown Goodyear welt and turn sewing machineshown and described in Patent No. 412,704, October 8, 1889. The -shoesto be operated upon are carried upon a freely movable jack, andcorrecting mechanism is provided for properly swinging the jack tomaintain the bottom of the channel adjacent to the point of operation ofthe sewy during the feed by imparting 'turning movements to the shaft S.The turning movements requisite for properly swinging the shoe duringthe sewing of the seam are imparted to the shaft S through chains 18 and19 passing about sprocket wheels 20, 21 and 22 secured to the Alower endof the shafts 8, 12 and 14 respectively.

The swinging movements vare imparted to the shoe when the needle is inengagement with the work, and the shoe will therefore be swung about thepoint of operation of the sewing mechanism. In order that the shoe maybe properly guided, the mechanism for swinging the shoe is so controlledby the contour of the channel is swung in accordance with thelongitudinal curvature of the channel at the point of operationof thesewing mechanism to maintain the bottom of the channel in line with thefeed. The-devices for thus swinging the shoe comprise a feeler 23arranged to engage the bottom or base of the channel substantiallyI thedistance of one stitch length in advance of the needle, and con-` nectedto control the mechanism which imparts turning movements to the jackturning shaft S. rThe feeler 23 is in the form of l a finger pivoted tothe lower end of the caris pivoted upon the end of an overhanging arm25. The feeler finger 23 is forced yieldingly toward the surface of thesole of the shoe by a spring 26 the compression -of which may beadjusted by an adjusting screw 27 (Fig-8). The fceler carrying lever 24is connected through a link 2S with a second lever 29, which is rierlever 24, which ing mechanism parallel with the direction of feed. Thesewing mechanism is mounted upon a support 1, and is provided with achannel guide 2, a back-gage 3, a feeding awl 4, and the usualcooperating stitch forming devices. The shoe to be operated upon iscarried upon a jack which is provided with heel and toe supports 5 andin turn connected through a link 30 with for supporting a lasted shoe.The jackis a lug 31 proyecting from a pulley 32. The secured upon theupper end of a sleeve 7 feeler is forced toward the base of the channelby spring 33. The pulley 32 is connected to turn in unison with a secondpulley 34 through a wire belt 35 which passes about the pulleys andabout guide pulleys 36, and may be tightened to takeup all slack andlost motion by a turn buckle 37. The pulley 34 is provided-with a.radially projecting arm 3S which is connected by a link 39 with one endof a sliding bar 40, the other end of which is connected by a link 41with one arm of a bell crank lever 42 (rig. 2). crank lever carries a 142 secured to a cam to intermittently withdraw from engagement with thebase of the channel, for a purpose to be explained. The

which surrounds a shaft 8 mounted in theouter end of a supporting arm 9.The sleeve is free to slide vertically upon the shaft, and is connectedto turn with the shaft by means of asycke 19 secured to the upper end ofthe shaft, and having .one of its arms slotted to embrace one of thearms 11 of the jack. rhe rear end of the supporting arm 9 is mounted toturn freely about a. shaft 12 which is mounted in bearings in the outerend of a second arm 13, the rear end lof which is in turn mounted toturn freely upon a shaft 14 mounted in the frame of the machine. Thesesupporting devices permit the jack to be moved freely in any directionin presenting a shoe to the sewing mechanism and in manipulating itdurroll engaging a cam shaft 48, and act-lng that the shoeI The otherend of the bell.

15 connected to one end of a the feeler finger '8 to bring the throughthe connect-ions between the feeler and roll carrying lever 42. Theposition of the roll 43 when the feeler is in engagement with the baseof the channel will depend upon the position of this point in thechannel with relation to the point in the channel where the stitch isbeing formed. The position of the roll determines the extent anddirection of the turning movement which is imparted to the jack turningshaft point in the channel engaged by the feeler into the line of feed.

`The mechanism through which the roll determines the rotary movementimparted to the shaft 8, comprises a reciprocating controller plate 44provided at its upper end with two oppositely inclined surfaces 45adapted to pass on opposite sides of the roll 43 when the roll is in midor neutral position. The plate 44 is pivotally mounted upon one end ot'a reciprocating `carrier lever 4G, the other end of which carries a rollengaging a cam 47 which is secured to a continuously rotating cam shaft48. The cam shaft 48 makes one revolution for each revolution of the camshaft of the sewing mechanism, so that the controller plate 44 isadvanced and retracted during each cycle of operations of the sewingmechanism.

` The lower end of the controller plate 44 is connected through a link49 with an arm 5C projecting through a sleeve 5l which is looselymounted upon a shaft A second arm 53 projects from the sleeve 5l, and isconnected by a link 54 with an arm or link 55. The rear end of the link55 is pivoted to a pivot block 56 mounted to slide in a segmental slotformed in an actuator lever 57. The actuator lever is pivotallysupported in a bearing 5S (Figs. 3 and A5), and the segmental slot inwhichthe pivot block 56 is mounted extends on opposite sides of thepivot of the lever. The lower end of theactuator lever carries a rollwhich is held in engagement with a. cam 59 on the cam shaft 48 lby aspring 60. The" actuator lever is thus reciprocated during each cycle ofol'icrations of the sewing mechanism. The other end of the link ispivotally connected to a sliding bar Gl, the end of which is connectedby a link G2 with one arm Iof a clutch operating lever 68. The other endof the. lever is 64 which engages a pinion formed on the hub ofthemen'iber GG of a clutch from which turning movements are in'iparted tothe jack turning shaft 8. The jack turning clutch is a. double-actingl-lorton clutch, the

'driven member of which consists of a disk 67 secured tc a hollow shaft68 (Fig. ti). This shaft carries a sprocket wheel (S9 which is connectedby a chain 70 with aI sprocket wheel 7l. The sprocket wheel 7l .inactiveby bell crank levers 7S.

provided with a gear segment is connected with a gear 72 engaging a gear73 connected with the sprocket wheel through which turning movements aretransmitted to the shaft clutch are forced in a,direction to wedgebetween the flange of the driving memberA Go' and the clutch surfaces'T6 on the driven member GT by spring-pressed pins TT, and areforccd'back to render the clutch The bell crank levers are forced in adirection to release the clutch pawls by a spring 79, and are actuatedto render the clutch inactive through a rod S() extending through thehollow shaft (SS and engaging the ends of the levers. The rod isactuated at proper intervals by a cam 8l on vthe cam shaft 4S whichengages one end of a lever S2, the other end of which is connected withthe upvper cnd of the rod 80.

So long as the point in the. channel which is engaged by the fceler 23isin the line of feed.` the roll 43 will bo positioned in mid or neutralposition, when the feeler engages the channel. When the roll. is in thisposition the inclined Surfaces 45 on the controller plate 44 will passon opposite sides of the roll without effecting. any swinging movementof the plate. rl`he connections between the. plate and the pivot block:iti are` such that under these conditions the pivotal connectionbetween the block and link 55 will be in line with the axis of theactuating lever 57. No turning movement will therefore be imparted tothe jack swinging clutch so long as the base of tho channel remains inthe line of feed. lVhenevcr the point of the channel engaged by thetcelcr is out of the line of feed, the roll l5-l will be positionedeither to the right or left of the neutral position a distanceproportioinll to the position of the point in the channel engaged by thelecler with relation to the line of feed. Now when the controller plate44 is raised, one of the surfaces will ride against the roll and swingthe plate about its pivot. This movement of the plate will through theconnections described shift the pivot block 5G to one side or the otherof the axis of the actuating lever 5T, so that during the active strokeof the lever the driving member (5o of the jack swinging clutch willoperate to swing the jack and shoe through the distance requisite torbringing the point of the channel engaged by the feeler in to the lineof feed. .ls soon as the roll 43 has been positii'mcd b v the fceler, itlocked and held during the advance movement ot' the controller plate bya clamp Sil arranged to engage the .sliding bar 40. This clamp iscarried in one arm oil i bell crank lever 84. the other ;.rni of whichcarries a roll engaging an operating cani R5 secured to the cam shaft4S. its soon as thtl controller plate The rolls 74 of the 44 has beenadvanced and has positioned the pivot bloclr 56, the bloclris locked inposition, and the ,ontroller plate is retracted to free the rolll, theclamp 83 being also released i may be immediately withdrawn from' thechannel, and so that the roll 43 may be again positioned by the feeler.The pivot block is thus locked by a clamp 86 arranged to 'engage asegment ST secured to the sleeve S6 is carried in one arm of a bellcrank lever S8, the other arm of which carries a roll engaging a cam S9on the cam shaft 4S. .A weight 90 is connecte with the sleeve 51 tocounterbalance the weight of the parts connected with the sliding pivotblock 56. The controller plate 44 and pivot block are returned toneutral position after each cycle of operations by a cam plate 91provided with a V-shaped mouth arranged to engage a roll on thecontroller plate. A spring 92 is connected with the link 49, and tendsto retract the controller plate.

The parts are shown in tl e position which they occupy after the shoefeeding movement of the feeding awl and channel guide has just beencompleted. Thefeeler has engaged the base of the channel and positionedthe roll 43, the controller plate 44 is retracted, the pivot block 56and the jaclr swinging clutch are in neutral position, ating lever is inits retracted position. Starting with the parts in this position, thecycle of operations performed during eac cycle of operations of thesewing mechanism is as follows: The roll 43 is locked in posi.- tion bythe clamp S3, and then the controller plate 44 is raised and by itsengagement with the roll 43, positions the pivot block 56 on theactuator lever 5T. The clamp 86 immediately locks the pivot bloclr inthis position, and then the lever 46 which carries the controller plateis released by its cam, so that'the controller plate may partiallyreturn to neutral position, thus freeing the roll 43. These movementstake place while the needle ofthe sewing mechanism is adthe work, andbefore the awl and channel guide have returned to their initialposition. The bell crank lever 42 is then actuated by its cam to retractthe feeler so that the feeding awl and channel guide may be retractedpreparatory to the next feed. and the channel guide may engage thechannel at substantiallythe point which was engaged by the feeler.During the return movement of the awl and channel guide, the actuatinglever 5T is rocked by its crm to operate the driving member 66 of thejack swinging clutch, so that the swinging movement of the shoe takesplace while the needle is still in the stock.

51. The clamp During the feed of the shoe the'jaclr swinging clutch isdisengaged, and the actuating lever is returned and the actuso that thefeeler finger1` to retracted position, the clamp 86 being released sothat the plate 44 may be returned to its retracted position. As the feedof the shoe is completed, and the awl and channel guide are disengagedfrom the channel, the cam 42 releases the bell crank lever 42, so thatthe feeler is again advanced and engages the channel, preparatory to thenext cycle of operations. Thus during each cycle of operations thefeeler engages the channel at a point in advance of the needlesubstantially equal to each feeding movement of the shoe and sets thejack swinging mechanism, so that this point in the channel is swung intothe line of feed where it will be properly engaged by the channel guideand awl.

ln sewing shoes having substantially flat soles, the shoe may bemaintained in proper relation to the sewing mechanism by the swingingmovements imparted to the shoe. To insure the proper engagement of thechannel guide with the base of the channel in sewing shoes the soles ofwhich have a moderate longitudinal curvature, it may be found desirableto mount the channel guide and awl upon the vfeed slide in such mannerthat they may move vertically to accommodate themselves to the verticalposition of the surface of the sole, and to provide centering levers 93and cams 94 for bringing the channel guide and awl into proper verticalrelation to the needle previous to the passage of the needle through thestock, as is more fully explained in Patent No. 1,03(), 0423, June 18,1912.

In order to relieve the needle or other device of the sewing mechanismfrom the strain to which they would otherwise be subjected during theswinging of the jack, additional devices are provided for constrainingthe jack to swing'about the point of operaj the yolze i l l tion of thesewing devices. 1n the construction shown these devices consist of aclamp, the jaws 95 and 96 of which are arranged to grip a plate 97. Theplate 97 is secured to 10 so that it turns with the jack and has anoutline corresponding generally to the shape of a shoe sole, so that themarginal portion of the plate may travel between the jaws of the gripperas the jack is mover longitudinally and swung during the sew* ingoperation. The jaws of the clamp are so arranged that a line passingthrough the ioint of operation ofthe sewing mechanism, and parallel withthe axis of the jack turn- S, will pass through the axis of the jaws.lVhen the clamp is engaged with the plate, therefore, it will form apivot about which the 'jack will swing when the jaclr turning shaft isrotated, and as this pivot is in line with the point efcperatien of thesewing mechanism, the cla "p constrain the jaclr to swing about ofoperation, and will relieve tl Y .Y which the needle would other.

ing sha-ft on the jaw jected. The jaws of the pivot clamp are p rovidedwith studs -98 for engaging the opposite sides of the plate, and thesestuds are so mountedlthat they may turn freely in the jaws of thegripper as the jack and plate 97 swing. The movable gripper jaw 9G isactuated to intermittently engage the gripper with the plate 97 by a cam99 arranged to `engage a. lever 100 which is pivoted on the gripper jawand transmits a gripping pressure to the jaw through a spring similar tothe spring 101 shown in Fig. 13.

I'ln order to assist the awl in feeding the shoe, or to relieve it ofthestrain incident to overcoming the inertia and friction of the jacksupporting devices, a supplemental feeding 'mechanism is providedforimparting feeding movements to the jack in unison with the feedingmovements of the awl. As shown, the supplemental feeding devices consistof a feeding gripper arranged to act on the plate 97. The feedinggripper comprises an arm 102 pivotally mounted in a bracket 103, andprovided at its forward .end with a freely turning'stud 104i forengaging the under side of the plate 97. The movable jaw 105 of thefeeding gripper is pivoted on .the plate 102, and is provided with apivoted gripping stud 106 at its forward end. `The jaw 105 is actuatedto intermittently grip the plate 97 by a cam 107 arrangedito engage theend of a lever 108 which is pivoted 105 and imparts a clalnping pressureto the jaw'through the spring 101 above referred to. The feeding gripperis actuated to impart feeding movements toithe` plate 97 and connectedjack through an arm 109 which projects from the hub ofthe .arm 102 andis connected by a, link 110 with one armY of a bell crank lever 111. Theother arm of the bell crank lever carries a roll which is held inengagement with a cam 112 by a spring 113. The link 110 is adjustahlyconnected to the arm of the bell crank lever 111, so that the feedingmovement of the gripper may be adjusted to correspond to the feedingmovement imparted to the shoe by the feeding awl. In order that theoperator may disengage both the feeding and pivot grippers from theplate, in case either of them are gripping the plate when it is desiredto swing the jack out of position, the

movable jaws 96 and 105-are' extended rearwardly into position to beengaged by a cam 114 formed on the upper end of a stud 115. This cam isprovided with an operating handle 110 through which it may be turned todepress the rear ends of the movable gripper jaws and thus disengage thefront ends of the jaws from the plate 97.

The cams for actuating the pivot and feeding gripper-s are secured on ashaft 117 which is continuously driven andmakes one revolution for eachrevolution of the cam shaft of the sewing mechanism. The cam 99 is sotimed that the pivot gripper is engaged with the plate 97 when thecorrecting mechanism is operated to swing the` jack, and is disengagedfrom the plate at other times. The cams 107 and 112 are so timed thatthe feeding' gripper engages and'feeds the forward plate during thefeeding movement of the awl, and is disengaged from the plate andreturned to initialposition during the return of the feeding awl.

The various mechanisms of the machine are driven from a main drivingshaft 118 through a suitable form of clutch which is under -the controlof the operator. The driving shaft is connected through a chain 119 witha shaft 120. The cam shaft 121 of the sewing mechanism is driven fromthe shaft 120 through beveled gearing and a shaft 122. ,f The cam shaft117 is driven from the shaft 120 through the chains 123, 124 and 125,and the cam shaft 48 for the correcting mechanism is driven through thechains 123 and 126, the connections being such that the cam shafts L18and 117 each make one revolution for each revolution of the cam shaft121.

While` the invention has been illustrated and explained in connectionwith its application to mechanism for swinging the shoe during theoperation thereon of inseam sewing me'chanism, and certain features ofthe invention relate more particularly to such a machine and mechanism,it will be understood that the broader features of the invention may' beembodied in machines for performing other operations upon a shoe, or inmechanisms for otherwise correcting the relative position of the shoeand means for operating thereon during the transfer of the pqint ofoperation of the operating means 'around the shoe to maintain the shoeand operating means in proper relation. It will also be understood thatthe specific construction and arrangement of the parts is not materialto the broader features of the invention, and may be varied and modifiedto suit the type of machine in which the inventien is embodied, and the-character of the corrective movements which are to be effected, withoutdeparting from the in vention.
